plot_rgl: Low level triangulation mesh plotting

Description

Plots a triangulation mesh using rgl.

Usage

plot_rgl(x, ...)
lines_rgl(x, ..., add = TRUE)
# S3 method for fm_segm
lines_rgl(
  x,
  loc = NULL,
  col = NULL,
  colors = c("black", "blue", "red", "green"),
  ...,
  add = TRUE
)
# S3 method for fm_mesh_2d
plot_rgl(
  x,
  col = "white",
  color.axis = NULL,
  color.n = 512,
  color.palette = cm.colors,
  color.truncate = FALSE,
  alpha = NULL,
  lwd = 1,
  specular = "black",
  draw.vertices = TRUE,
  draw.edges = TRUE,
  draw.faces = TRUE,
  draw.segments = draw.edges,
  size = 2,
  edge.color = rgb(0.3, 0.3, 0.3),
  t.sub = seq_len(nrow(x$graph$tv)),
  visibility = "",
  S = deprecated(),
  add = FALSE,
  ...
)
# S3 method for fm_segm
plot_rgl(x, ..., add = FALSE)
# S3 method for fm_segm_list
plot_rgl(x, ...)
# S3 method for fm_segm_list
lines_rgl(x, ...)

Value

An rgl device identifier, invisibly.

Arguments

x

A fm_mesh_2d() object

...

Additional parameters passed to and from other methods.

add

If TRUE, adds to the current plot instead of starting a new one.

loc

Point locations to be used if x$loc is NULL.

col

Segment color specification.

colors

Colors to cycle through if col is NULL.

color.axis

The min/max limit values for the color mapping.

color.n

The number of colors to use in the color palette.

color.palette

A color palette function.

color.truncate

If TRUE, truncate the colors at the color axis limits.

alpha

Transparency/opaqueness values. See rgl.material.

lwd

Line width for edges. See rgl.material.

specular

Specular color. See rgl.material.

draw.vertices

If TRUE, draw triangle vertices.

draw.edges

If TRUE, draw triangle edges.

draw.faces

If TRUE, draw triangles.

draw.segments

If TRUE, draw boundary and interior constraint edges more prominently.

size

Size for vertex points.

edge.color

Edge color specification.

t.sub

Optional triangle index subset to be drawn.

visibility

If "front" only display mesh faces with normal pointing towards the camera.

S

Deprecated.
